CAR-SEAL.

SPECIFICATION forming' part of Letters Patent No. 548,568, dated October22, 1895. application nea December 6, 1894. sain no. 630,952. (no man Toall whom t 'may concern:

Be it known that I, ALEX GUsrAvn MALM- STROM, acitizen of the UnitedStates, and a resident of Chicago, Cook county, Illinois, have inventedcertain nen7 and useful lmprovements in Car-Seals,of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, and to the letters of reference marke thereon. f

The object of my invention is to provide a cheaply-constructed car-sealwhich can be locked by hand Without requiring the use of anyspeciallyconstructed tool or implement of any kind and which cannot beunlocked exclept by cutting the loop or breaking the sea My inventionconsists of the usual metallic loop or strap and a seal, in which oneend of the loop is originally permanently fastened and which has apocket that has locking-hooks inserted therein projecting from itssides'in such manner that when the originally free perforated end of thestrap is inserted in the pocket its withdrawal is prevented,substantially as hereinafter fully described, and as illustrated in thedrawings, in Which- Figure l is a perspective viewr of my invention.Fig. 2 is a longitudinal central View of the seal with the ends of theloop secured therein, taken on au enlarged scale. Fig. 3 is a detailview showing, on an enlarged scale, the detached originally free end ofthe loop or strap; and Fig. e is a detail view, on an enlarged scale, ofthe Ueshaped metallic strip located Within the pocket of said seal.

Referring to the drawings, A represents a narrow strap or loop of sheetmetal, one end of which is permanently secured in the seal B, preferablyby being molded therewith, as

vshown in the drawings, and the other end C preferably of a rectangularshape, and it. is recessed longitudinally from one end, so as to form a'pocket d of such Width as to freely admit the insertion of end C oftheloop. Placed and permanently secured Within this pocket is the lookD. This lock consists of a U-shaped strip of sheet metal of about thesame Width as the pocket d. Itis originally made of a single lengthtwice the depth of the pocket, and it is bent double, so that one of thelegs lr thus formed Will lie fiat against one side of Vsaid pocket andthe other leg 7a will lie flat against the other broad side thereof insuch manner that when the free end of the strap or loop is inserted inthe seal it will pass between said legs. Now in order to prevent thewithdrawal of end C when inserted in the seal I have provided both ofsaid legs h and 7a with a hook e and g, respectively, which preterablyconsist ot' tongues stamped out of said legs, the free ends of whichproject inward a slight distance and then extend longitudinally towardthe closed end of the pocket. When the end C of theloop is pushed intothe pocket, it forces the hooks back out of the way; but when the endsof said hooks come next or in register with the openings c and b of saidend they spring through them and prevent the Withdrawal of said end. lcan, if desired, dispense with one of said hooks, although I much preferthe use of both. If desirechl can provide one or both of the hooks h and7n with a slight spur oc near their extremity, which will catch underthe end edge of end C or the adjacent edge of the openingb, as shown.This serves, after the end C is once caught and held by the hooks, toprevent any longitudinal movement of the said end.

What I claim as nenr is 1. As an' article of manufacture a car-sealconsisting of a suitable strap orloop, a suitable metallic seal having apocket therein, and a U-shaped strip of metal secured in said pockethaving a tongue or hook projecting from each leg of the saine into andtoward the closed end of said pocket and said hooks each being providedWith a spur projecting from near its free extremity backward toward itssecured end, said strap having one end permanently secured to said sealand the other provided with an opening therein so that IOO when thrustin said pocket, said hooks will are provided with spurs which pointtoward catch and with the aid of said spurs eieetuthe secured endthereof, and said loop having ally look the same. one end permanentlysecured in said seal,and

2. As an article of manufacture a car-seal the other normally free endprovided with 15 5 consisting ot' a suitable strap or loop, and areference to said hooks, and so thatwhen said suitable metalliosealhavinga pocket therein, end is inserted in the pocket of the seal it isa tongue or hook projecting from each of the locked therein.

broadsides of said pocket in such manner as ALEX GUSTAVE MALMSTROM. tofollow one another, said tongues or hooks Vituesses: 1o extend and pointtoward the closed end of M. C. BERGLW,

said pocket, and near their free extremities CARL. WEDBERG.
